Sign in to save and follow
Oryza Sativa (Rice) Extract appears in Korean sunscreens and essences for soothing and tone claims. Composition varies with extraction method (water, glycerin, ferment co-products)[1].
What it does
Marketing leans on traditional rice water use and in-vitro antioxidant/soothing readouts. It is not a regulated UV filter — SPF still comes from filters such as diethylamino Hydroxybenzoyl Hexyl Benzoate[1].
The evidence
Human RCTs on cosmetic rice extract alone are sparse; grade emerging/limited depending on claim[1].
How to use it
Treat as supporting botanical context on a sunscreen or serum label, not the reason the SPF works.
Evidence by claim
Graded separately; the entry grade is the best-supported claim
Soothing/antioxidant botanical support in leave-ons[1]
EmergingDepends on extract standardisation.
